Inclusion List

A mechanism letting the decentralised validator set specify transactions a block builder must include, so a few centralised builders can't quietly censor valid, fee-paying transactions by omitting them. Modern designs (e.g. FOCIL, EIP-7805) spread the power to build the list across many validators so the mechanism itself resists capture. It upgrades censorship resistance from 'included eventually if some builder is honest' to 'inclusion enforced by the validator set'.
